In this study, we describe our experience with the feasibility and safety of CA in patients with a preexisting Watchman LAAO device.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a retrospective multicenter AF registry of 60 patients with Watchman LAAO device who underwent CA for AF. Baseline clinical and procedural characteristics of the included subjects were retrieved from review of medical records and were analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean age was 72.7 \u00b1 4.9 years and the mean CHADS2 score was 2.3 \u00b1 0.6. All patients had successful pulmonary vein isolation (PVI). The left atrial appendage (LAA) was electrically active in 34 (56%) while reentrant tachycardia and AF triggers were seen in 17 (28%) patients. Electrical isolation was attempted in these 17 patients with only 10 achieving complete LAA isolation. Repeat imaging showed new peri\u2010device leaks in 30% (12\/40) patients, while new significant peri\u2010device leaks (\u22655 mm) were noted in 10% (10\/40) of patients after RFA, respectively, requiring continuation of oral anticoagulation. There were a higher proportion of patients with severe peri\u2010device leaks (\u22655 mm) after LAA isolation. However, &gt;50% of those leaks sealed off on follow\u2010up transesophageal echocardiogram.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>AF ablation is a feasible and safe in patients with preexisting Watchman LAAO device. Electrical isolation of the LAA could be difficult and when attempted can result in increased risk of short\u2010term peri\u2010device leak and recurrence of AT\/AF in almost all patients.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jce.13148","type":"journal-article","created":{"date-parts":[[2016,12,12]],"date-time":"2016-12-12T06:08:48Z","timestamp":1481522928000},"page":"139-146","source":"Crossref","is-referenced-by-count":40,"title":["Catheter Ablation for Atrial Fibrillation in Patients With Watchman Left Atrial Appendage Occlusion Device: Results from a Multicenter Registry"],"prefix":"10.1111","volume":"28","author":[{"given":"MOHIT K.","family":"TURAGAM","sequence":"first","affiliation":[{"name":"Division of Cardiovascular Disease University of Missouri Hospital and Clinics  Columbia Missouri USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"MADHAV","family":"LAVU","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Diseases, Cardiovascular Research Institute University of Kansas Hospital and Medical Center  Kansas City Kansas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"MUHAMMAD R.","family":"AFZAL","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Diseases, Cardiovascular Research Institute University of Kansas Hospital and Medical Center  Kansas City Kansas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"VENKAT","family":"VUDDANDA","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Diseases, Cardiovascular Research Institute University of Kansas Hospital and Medical Center  Kansas City Kansas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"MOHAMMAD\u2010ALI","family":"JAZAYERI","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Diseases, Cardiovascular Research Institute University of Kansas Hospital and Medical Center  Kansas City Kansas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"VALAY","family":"PARIKH","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Disease University of Missouri Hospital and Clinics  Columbia Missouri USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"DONITA","family":"ATKINS","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Diseases, Cardiovascular Research Institute University of Kansas Hospital and Medical Center  Kansas City Kansas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"SUDHARANI","family":"BOMMANA","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Diseases, Cardiovascular Research Institute University of Kansas Hospital and Medical Center  Kansas City Kansas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"LUIGI","family":"DI BIASE","sequence":"additional","affiliation":[{"name":"Montefiore Medical Center  Bronx New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"RODNEY","family":"HORTON","sequence":"additional","affiliation":[{"name":"Texas Cardiac Arrhythmia Center  Austin Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"RONG","family":"BAI","sequence":"additional","affiliation":[{"name":"Beijing Anzhen Hospital Capital Medical University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"VIJAY","family":"SWARUP","sequence":"additional","affiliation":[{"name":"Arizona Heart Rhythm Institute  Phoenix Arizona USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JIE","family":"CHENG","sequence":"additional","affiliation":[{"name":"Texas Heart Institute  Houston Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ANDREA","family":"NATALE","sequence":"additional","affiliation":[{"name":"Texas Cardiac Arrhythmia Center  Austin Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"DHANUNJAYA","family":"LAKKIREDDY","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Diseases, Cardiovascular Research Institute University of Kansas Hospital and Medical Center  Kansas City Kansas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,1,19]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"crossref","first-page":"2246","DOI":"10.1016\/j.jacc.2014.03.021","article-title":"2014 AHA\/ACC\/HRS Guideline for the management of patients with atrial fibrillation: Executive summary.
